TUBE CGNNECTION FOR HOT-WATER BOTTLES.

Specification of Letters Patent.

Application filed September 4, 1917. Serial No. 189,442.

hose so that the tube or hose can be convenie-ntly used without any danger. of the same twisting, breaking or cracking at its connection with a hot water bottle.

Our invention further aims to provide a simple, durable and inexpensive tube connection for a hot water bottle or similar receptacle that permits of the tube being easily and quickly detached so that a stopper or plug may be substituted therefor, when it is desired to use the hot water bottle-without the tube or syringe attachment.

Our invention will be hereinafter specifically described and then claimed, and reference will now be had to thedrawing, wherein Figure 1 is a side elevation of a hot water tube, partly broken away and partly in section, showing the tube connection therewith, and

Fig. 2 is a side elevation of a modified form of connection.

In the drawing, the reference numeral 1 denotes a conventional form of hot water bottle having one end thereof provided with a filling funnel 2 and a tab 3, and the closed end with a tab 3 Fixed'in the funnel 2 is a plug 4. The plug 4 is made of fiber, wood or any suitable material, and a neck 5 of the bottle 1 is held in engagement with the concave wall of the plug 4 by wrappings of cord, wire or other clamping means generally designated 6.

The plug a is provided with the central opening 7 and the outer end of the opening is enlarged to receive a metallic sleeve 8 of less depth than the enlarged outer. end of the opening 7. The inner walls of the sleeve 8 are screwthreaded andare adapted to receive an exteriorly screwthreaded gland 9 having a head 10. The gland 9 and the head 10 have a longitudinal bore 11 providing clearance for the ehd of a syringe tube 12. The inner end of the syringe tube Patented Dec. 40, 1918.

12 is provided with aperipheral flange 13' and interposed between said flange and the gland 9 is a fiber washer 14. This washerprevents the flange 13 from being unnecessarily worn by contacting with the inner end of the gland 9, particularly when the gland is screwed too tight or far into the sleeve 8. With the gland 10 properly positioned, the flange 13 will permit of the tube 12 turning in said gland, and in this-manner said tube is not twisted, crackedorbroken at the lglanid while the syringe is being manipuate The head 10 permits of the gland 9 being tightened when it is desired to compress the flange 13 in the plug 4L thus positively agchor the tube 12 relative to said plug and avoid any leakage around the flange 10 of the tube, should such leakage occur.

In Fig. 2 of the drawing, there is illustrated a slight modification of our invention, wherein a nipple 15 extends througha plug 16 and is provided with a peripheral flange 17; A washer 18 is interposed between the flange lT and the plug IGandthe outer end of the nipple 15terminat'es in, a button 19, so that a section of hose or tubing may be fitted over the nipple. lVhen it is desired to use the hot wate bottle without the tube connection, an ordinary screw plug, such as generally used in the filling funnel 2, can be screwed into the sleeve 8 to close the plug 4.

While in the drawings, there are illustrated the preferred embodiments ,of our invention, it is to be understood that the structural elements are susceptible to such changes, in size, shape and manner of assemblage .as fall within the scope of the appended claim,

W hat we claim is 2-- v The combination of a hot water bottle having a neck, a plug in the neck thereof having a concave wall about which the bottle neck is secured, said plug having a central opening with the outer end thereof enlarged to form an annular seat in s'aidplug,

an interiorly screw threaded sleeve mounted having the inner end thereof provided with In testimony whereof We affix our signaa peripheral flange engaging the annular tures in presence of two'witnesses.
